Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 4:
The LT1993C-4 is guaranteed to meet specified performance from may cause permanent damage to the device. Exposure to any Absolute 0°C to 70°C. It is designed, characterized and expected to meet specified Maximum Rating condition for extended periods may affect device performance from –40°C and 85°C but is not tested or QA sampled reliability and lifetime. at these temperatures. The LT1993I-4 is guaranteed to meet specified
Note 2:
As long as output current and junction temperature are kept below performance from –40°C to 85°C. the Absolute Maximum Ratings, no damage to the part will occur.
Note 5:
This parameter is pulse tested.
